Question

Help would be greatly appreciated! Thanks! :)
How are the linings of the various digestive passageways adapted for their specific use ? Focus on the esophagus, stomach, small intestine and large intestine. =D

Answer 1

The esophageal wall is composed of smooth muscle, which helps in bowel movements, involuntary movements that are leading the bolus into the stomach. The intestinal mucosa is coated fabric resistant to low pH in the stomach, from the HCl produced by cells of the mucous itself. The smooth muscle is also present in small and large intestines, aiding the evacuation of stool
